Set in New York City, 1982, the book follows a dysfunctional family – detail-obsessed Carrie, constantly-angry Eli, their pot-smoking mother Viv and her teenage boyfriend, Arnie – who live in a one-bedroom apartment on the Upper West Side. One by one, they encounter a psychic, Miss Rosa, who lives ‘above the smaller dry cleaners’ and is desperate to share her life story with the family; a story that resonates disturbingly with their own lives.

‘It’s about the blur between kids and adults, sex and love, stories and real life,’ says Chassler of her latest publication. ‘It was a hard novel to write. I knew it was odd from the moment I started … though I tried to make it as pleasurably readable as possible, while respecting its increasingly bizarre aims. Hopefully I managed to juxtapose the plotless discomfort of the family with the deathbed story Rosa is attempting to concoct, to make sense of her life. In a way, it’s about the stories we think we’ve lived.’

Born in Madison, Wisconsin, in 1972, Nora Chassler grew up in New York, a city she writes about in immersive, extraordinary detail – almost as a character in its own right. She has an undergraduate degree in English from Hunter College, CUNY, and a Masters in Creative Writing from St Andrews. She has worked as a model and a social worker, and now lives in Edinburgh.

Her first novel, Miss Thing (2010) was described by The Herald as ‘Somewhere between Nabokov and Bret Easton Ellis … Chassler’s characters illicit real emotion. Their stories grip you to the last and leave you wanting more.’ The Independent said Chassler’s ‘shimmering debut’ ‘demands – and rewards – close attention. It’s clever, playful and often darkly funny. It’s also touching.’

Produced in a luxurious foil-finished paperback format by Scarborough’s Valley Press, Grandmother Divided by Monkey Equals Outer Space will be launched in an event at Edinburgh’s ‘Word Power Books’, on Monday 30th March, from 6.30pm.
